Application filed August 6, 1912. Serial No. 713,689.

To all whom it may concern:

Be it known that 1, JAMES S. PICKLES, citizen of the United States of America, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in W'ood-Trimmers, of which the fol lowing is a specification.

This invention pertains to wood trimmers and has for its object to provide a mechanism for trimming the ends of pieces of wood, either at right angles or at any other angle, so constructed as to do the cutting with the least possible force and with the least possible crushing of the wood. I accomplish this purpose by the construction shown in the accompanying drawings, in which- Figure 1, is a top plan view of the device, Fig. 2, is a side elevation thereof, Fig. 3, is a transverse vertical sectional view thereof taken on the line 33 of Fig. 1, and Fig. 4, is a transverse sectional view taken on the line 44 of Fig. 2.

The apparatus is shown mounted upon a platform 10. A horizontally arranged table 11 has underneath the same supporting ribs 12. Secured at one edge of the table 11 by the bolts 13 is a vertical frame 14 provided with two parallel downwardly curved grooves 15. A knife head 16 having beveled edges 17 has curved upper and lower ends adapted to fit the grooves 15 in the frame 14. The knives 18 are secured to the head 16 by bolts 19, with their cutting edges 20 extend ing upwardly and outwardly at an angle of approximately 45 degrees. To the side of the knife head 16 is secured a downwardly curved rack 21 and to the side of the frame 14: is secured a downwardly curved rack 22. Bet-ween the two racks 21 and 22 a sprocket wheel 23 is stationed in such a manner as to engage the racks. Attached to the sideof the sprocket wheel 23 is a link 2A adapted for, and in which the end of a lever 25 is, inserted. The knife head 16 is adapted to move backward and forward in the grooves 15. Gages 26 and guides 27 are provided at the upper surface of the table 11 for setting the angle of the wood for cutting as desired. By the operation of the lever 25 connected with the sprocket wheel 23 the head 16 is forced backward and forward along the grooves 15, carrying the knives 18 with it.

A piece of wood 28 desired to be trimmed is laid on the top surface of the table 11 and adjusted to the proper angle by the gage 26 and guide 27, with the end desired trimmed protruding underneath the cutting edge 20 of the knife 18 as shown in Fig. 2, the lever 25 actuated throwing the head 16 and the knife 18 toward the wood 28, the cutting edge 20 of the knife 18 first striking the upper corner of the wood as shown in Fig. 2 and being forced through the same by a forward and an upward stroke, thus severing the wood strictly by what is known as the draw cut. The cut is the same as the butcher would use in cutting meat, the mode of effecting the out being different in that in the construction the cut is forced and a butcher draws the knife.

Having thus described my invention what I claim as new and useful and desire to secure by LettersPatent, is,

In a wood trimmer, a horizontally arranged table, a vertically arranged frame at one side of the table and attached thereto, having two parallel grooves curved on an arc struck from the center above the table, a knife head with beveled sides adapted to fit and to run in said grooves, knives attached to said knife head with their cutting edges set at an outward and upward angle, together with means for actuating said knife head along the said grooves to trim blocks of wood placed on said table and extending underneath the blades.

In testimony whereof I affix my signature in presence of two witnesses.
